The 45-year-old singer, who recently split from estranged husband Gavin Rossdale after 13 years of marriage, is currently working on her third solo album and can't wait to hit the road with their three children, Kingston, nine, Zuma, seven, and Apollo, 17 months.
She said: "I'll just put my three kids in a van and say, 'Let's do this!' They can sell T-shirts."
The 'Voice' USA mentor is also looking forward to sharing her new music with fans.
She added: "I've written about 15 songs - they're about my life. It's like the egg and the sperm just went together and created these songs. I feel like I'm in a place of, 'Wow, I have this gift - use it, share it!'"
The No Doubt star admits a lot has changed since her first major tour in 1997.
She explained to Us Weekly magazine: "When I started out, I didn't know anything about fashion. I had no money and didn't go shopping - I went to a s**t fabric store. Now, I love make-up and getting dressed up. It never gets old for me."
